Necrotic ulcers of the feet are a dangerous complication of the diabetic foot syndrome. Besides peripheral vascular disease (PVD) peripheral neuropathy is an important factor in the pathogenesis of necroses. We examined whether the reserve of circulation during reactive hyperemia at the feet of
Diabetic foot is traditionally attributed to a triad of neuropathy, ischemia and infection. Cellular hypoxia in diabetic foot can neither be attributed to an occlusive large artery disease (which are mostly patent) nor to the so called diabetic small vessel disease (where such occlusion was never
Hypoxia inducible factor 1 alpha (HIF-1α) is a key regulator of the genes involved in the cellular response to hypoxia. This study aims to determine the HIF-1α gene polymorphism and its association with protein expression in diabetic subjects with and without diabetic foot ulcers (DFU). A total of
OBJECTIVE
Adaptation to low oxygen tension (hypoxia) in cells and tissues leads to the transcriptional induction of series of genes and the primary factor mediating this response is the hypoxia-inducible factor-1α. This study was designed in order to examine the HIF-1α gene polymorphism, p582s
Few topics in diabetic wound management generate as much "heated" discussion as hyperbaric oxygen (HBO). Hyperbaric oxygen is an intermittent inhalation therapy in which the patient breathes oxygen at greater than 1 atm of pressure. This requires placement of the patient into a sealed vessel
Complications associated with diabetes are often expensive to treat, and commonly include foot ulceration. While most diabetic foot ulcers heal with standard treatment, when standard treatment measures fail, adjunctive therapies must be considered. We review the theory and evidence for the use of
Daprodustat, a small-molecule inhibitor of prolyl hydroxylases, prevents breakdown of hypoxia-inducible factor (HIF), leading to increased transcription of HIF-responsive genes. This randomized, placebo-controlled study evaluated the safety, tolerability, and pharmacokinetics of a topical
Clinical neurological studies, blood pressure measurements and some haematological investigations were performed on a random sample of forty-four patients, at the Diabetes Out-Patient Clinic of the University Hospital of the West Indies (UHWI), to examine some of the factors that predispose to the
BACKGROUND
Uncontrolled deformity, deep infection, and/or ischemia-hypoxia are highly associated with healing challenges of diabetic foot ulcers (DFUs). This paper reports the occurrences of these factors that the authors label the "Troublesome Triad" (TT) in a prospective series of 62 patients with
Reduced life expectancy has resulted from an increased incidence of chronic complications in patients with diabetes. The diabetic foot is one of these complications and generally presents together with diabetic neuropathy and vascular insufficiency. Hypoxia-inducible factor-1α (HIF-1α) is important
UNASSIGNED
To review the effect of dipeptidyl peptidase 4 (DPP-4) inhibitors on the wound healing and its mechanisms in chronic diabetic foot ulcers.
UNASSIGNED
The latest literature concerning DPP-4 inhibitors for chronic diabetic foot ulcers was extensively reviewed, as well as the potential
A total 37 patients suffering from end stage-IV Fontaine (CLI and diabetic foot) with an ulcerated limb in whom all previous therapeutic strategies failed (e.g. surgical revascularization and endovascular repair) were selected and underwent local transplantation of Autologous Bone Marrow Stem Cells
The widespread use of HBO as an adjunctive treatment of diabetic foot ulcers has been founded on weak scientific evidence, but the consistency in positive outcomes in trials evaluating HBO on ulcer healing is noteworthy, not least as these results are in concert with data from in vitro and
Diabetic infected foot is the outcome of progressive vascular and neurological damage caused by persistent chronic hyperglycemia. Due to acute hypoxia and infection, the tissues develop extensive necrosis and gangrene, which often require amputation. The decision regarding the level of amputation
NTRODUCTION Diabetic foot ulcers are a chronic complication in patients with diabetes mellitus. They appear as a result of the combination of diabetic polyneuropathy and angiopathy, and in many cases require amputation of the affected extremity. Clinical trials have demonstrated that repeated local
